network. Consult the application’s documentation to determine if it supports

operation over a network.

What is the IEEE 802.11b standard? The IEEE 802.11b Wireless LAN standards

subcommittee formulates the standard for the industry. The objective is to

enable wireless LAN hardware from different manufacturers to communicate.

What IEEE 802.11 features are supported? The product supports the following

IEEE 802.11 functions:

• CSMA/CA plus Acknowledge protocol

• Multi-Channel Roaming

• Automatic Rate Selection

• RTS/CTS feature

• Fragmentation

• Power Management

What is BSS ID? A specific Ad-hoc LAN is called a Basic Service Set (BSS).

Computers in a BSS must be configured with the same BSS ID.

What is SSID? An Infrastructure configuration could also support roaming

capability for mobile workers. More than one BSS can be configured as an

Extended Service Set (ESS). Users within an ESS could roam freely between

BSSs while maintaining a continuous connection to the wireless network sta-

tions and Access Points.

What is ISM band? The FCC and their counterparts outside of the U.S. have set

aside bandwidth for unlicensed use in the ISM (Industrial, Scientific and

Medical) band. This presents a truly revolutionary opportunity to place con-

venient high speed wireless capabilities in the hands of users around the

globe.

What is Spread Spectrum? Spread Spectrum technology is a wideband radio

frequency technique developed by the military for use in reliable, secure, mis-

sion-critical communications systems. It is designed to trade off bandwidth

efficiency for reliability, integrity, and security. In other words, more band-

width is consumed than in the case of narrowband transmission, but the trade-

off produces a signal that is, in effect, louder and thus easier to detect, pro-

vided that the receiver knows the parameters of the spread-spectrum signal

being broadcast. If a receiver is not tuned to the right frequency, a spread-

spectrum signal looks like background noise. There are two main alternatives,

Direct Sequence Spread Spectrum (DSSS) and Frequency Hopping Spread

Spectrum (FHSS).
